LEM-320: delivery record
On this page
The supplier files LEM-320 as a Notifier loop expander for fire-alarm systems. The first and second source photographs could not be retrieved, so no photograph was visually reviewed under the first-photo/maximum-second-photo rule. This entry preserves the available source media and distinguishes supplier claims from verified physical markings.
Identification and delivery details
The May 23, 2025 upload note describes one new unit with a one-year warranty. A separate March 11, 2026 entry describes three new, packaged units, also with a one-year warranty, and states Notifier and Made in China. These are two dated entries, totaling four noted units; the photographs do not independently confirm their allocation.
The older note gives weight 1 kg, while the March entry and structured field give 0.5 kg. The different figures are preserved without assuming they are bare-unit and packed weights. A weighing basis was not supplied.
The complete list contains twenty-one photographs and two videos. Twelve photographs and one video remained GET404 after a clean full retry and per-file directory checks. Nine photographs and the other video downloaded completely; their files and checksums are retained, but none was visually reviewed.
The description mentions ONYX and several NFS panel families. With no reviewed physical label or functional test, this record cannot establish the exact board revision, host compatibility, allowable loop wiring or device capacity. The expander should not be represented as a complete fire-alarm controller.

No source photograph was visually reviewed: the permitted first and second images are inaccessible. Later available photographs are retained with neutral source-position captions, and the available video remains unreviewed. The twelve failed image files and failed video are listed in the archive and excluded from this page; no dead media link is embedded.
Matching this part
Obtain a readable model and revision label from the actual proposed module, along with clear connector and mounting photographs. Compare those details with the removed expander and confirm host-panel support using the applicable manufacturer documentation.
Identify the required companion control module and included hardware separately. Confirm the dated supply entry, quantity, condition, test evidence, warranty and weight basis before treating the source description as a replacement specification.
